ALLOY.

No Drawing.

To all whom it may concern Be it known that I, JOSEPH MONVILLE, a citizen of the United States, residing at Hubbell, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Alloys, of which the following is a specification.

This invention has as its object to provide an alloy which will possess such characteristics as will render it especially valuable in the manufacture of sheathing for the hulls of vessels to prevent the adherence of barnacles thereto and in the manufacture of marine boilers, paddle Wheel buckets, piston rods, valve stems, valve seats, valve springs, shell bands, bearings, and in fact any article or machine part Where great tensile strength and elasticity is required and for any purposes for Which brass is ordinarily employed.

The alloy of the present invention is prepared by mixing and fusing the following metals in' the percentages stated:

Copper 95.50070 Iron 3.000% Tin 525%- Zinc .625% Nickel 250% Specification of Letters Patent. Patented Sgpt, 26, 1916, Application filed April 27, 1916. Serial No. 93,964.

An alloy comprising the above mentioned metals has been found by test to possess a tensile strength of approximately 62,683 lbs. per square inch and to have an elastic limit of approximately 54,104: lbs. per square inch.

Also it has been found by test that the elongation of the alloy is 18.30 contraction 63.74: per cent.

While it is preferred for ordinary purposes to combine the metals comprising the alloy in the proportions above stated, these proportions may be varied so as to vary the tensile strength to any degree between 32,000 lbs. to the square inch and 150,000 lbs. to the square inch.

Having thus described the invention, what is claimed as new is:

An alloy consisting of copper,;steel, tin, zinc, and nickel in approximately the proportions of copper 95.5%,- iron 3%, tin .625%, zinc .625% and nickel 25%.

In testimony whereof I affix my signature.
